摘要：

背景：加速正畸牙移动速度，缩短疗程，多年来一直是国内外学者的研究热点。有学者提出了牙周膜牵张成骨的概念，是牵张成骨的一种特殊应用形式。这一方法应用于临床正畸治疗，可快速移动尖牙，显著缩短治疗时间，提高临床矫治效率，为解决疗程较长这一临床难题提供了一条新的思路。
目的：建立生物相似性和力学相似性较高的牙周膜牵张成骨术快速移动尖牙的三维有限元模型。
方法：通过64排螺旋CT扫描，获得颞下颌关节、下颌骨、下颌牙列截面影像的DICOM数据。采用Mimics软件、Geomagic Studio8.0软件、Unigraphics NX软件、Ansys11.0软件相结合的方法，建立包括颞下颌关节、下颌骨、下颌牙齿及牙周膜的牙周膜牵张成骨术快速移动尖牙的三维有限元模型。
结果与结论：实验建立了由39 060个单元，76 103个节点组成的牙周膜牵张成骨术快速移动尖牙的三维有限元模型，还可根据研究需要，添加或删除组件。

Abstract:

BACKGROUND: To accelerate orthodontic movement speed and shorten treatment course is the focus in recent studies. Some researchers propose the concept of peridental ligament distraction osteogenesis, which is one special application type of distraction osteogenesis. This method has been used in clinical orthodontic treatment and can accelerate canine teeth movement, significantly shorten treatment duration, and improve correction efficacy. It provides a novel approach to shorten long treatment course.
OBJECTIVE: To establish three-dimensional finite element model (3-D FEM) with better similarity of rapid canine tooth movement in periodontal ligament distraction.
METHODS: By using scanning of spiral CT with 64 rows, the sectional image data in DICOM of TMJ, mandible and lower tooth were acquired. With the help of Mimics, Geomagic Studio 8.0, Unigraphics NX and Ansys 11.0 software, the 3-D FEM of rapid canine tooth movement in periodontal ligament distraction, including TMJ, mandible, lower tooth and periodontal ligament was established.
RESULTS AND CONCLUSION: A 3-D FEM of rapid canine tooth movement in periodontal ligament distraction was established, which consisted of 39 060 elements and 76 103 nodes. Furthermore, we could add or delete the framework according to different research demands.
